Detailed Description

The QEditorFactory class is used to create editor widgets for QVariant data types.

Each editor factory provides the createEditor() function which given a QVariant will create and return a QWidget that can edit that QVariant. For example if you have a QVariant::String type, a QLineEdit would be the default editor returned, whereas a QVariant::Int's default editor would be a QSpinBox.

If you want to create different editors for fields with the same data type, subclass QEditorFactory and reimplement the createEditor() function.

Member Function Documentation

QEditorFactory::QEditorFactory ( QObject * parent = 0, const char * name = 0 )

Constructs an editor factory with parent parent, called name.

QEditorFactory::~QEditorFactory ()

Destroys the object and frees any allocated resources.

QWidget * QEditorFactory::createEditor ( QWidget * parent, const QVariant & v ) [virtual]

Creates and returns the appropriate editor for the QVariant v. If the QVariant is invalid, 0 is returned. The parent is passed to the appropriate editor's constructor.

Reimplemented in QSqlEditorFactory.

QEditorFactory * QEditorFactory::defaultFactory () [static]

Returns an instance of a default editor factory.

void QEditorFactory::installDefaultFactory ( QEditorFactory * factory ) [static]

Replaces the default editor factory with factory. QEditorFactory takes ownership of factory, and destroys it when it is no longer needed.
